The CMA were concerned that customers in these areas could face price increases or a reduction in the choice of the products and services in-store.

“All affected team members will be protected by transfer of undertaking (protection of employment) regulations, with their employment being transferred to a new optical retailer,” Mr Lawson added.

He also said that ahead of the CMA’s final decision, Vision Express’ focus will remain on ensuring a quick and smooth transition for the benefit of its employees and customers.

GrandVision, owner of Vision Express, reported in its 2017 half-year results in August that the company expects to complete the acquisition in the final quarter of 2017, taking its total to over 598 practices.
